Abstract
A kind of high heat conduction type backboard used for solar batteries and preparation method thereof, belongs to solar module technical field.Step：Heat-conducting type mylar is taken as basic unit；By 40 60 parts of fluorine-containing copolymer resinses, 10 30 parts of plexiglass, 10 30 parts and flow ability modifying agent ＜ 5 parts mixings of heat filling, compound is put into melting extrusion in double screw extruder, afterwards by casting film-forming in blown film in pellet input inflation film manufacturing machine or casting machine, weathering layer is obtained；By 40 60 parts of fluorine-containing copolymer resinses, 10 30 parts of plexiglass, the mixing of 10 30 parts and flow ability modifying agent ＜ 5 parts of heat filling, the internal layer of the fluorinated copolymer layer for then obtaining with the addition of heat filling；Compound.Have excellent weather-proof, ageing-resistant, insulating properties, contamination resistance, water vapor transmittance little；There is the heat dispersion that stands out from one's fellows, improve the photoelectric transformation efficiency of cell piece；Processing step is terse and without harsh technical factor.
Description
Technical field
The invention belongs to solar module technical field, and in particular to a kind of high heat conduction type back of the body used for solar batteries
Plate, and further relate to its preparation method.
Background technology
Solaode is also referred to as solar-energy photo-voltaic cell, and its overall structure is known to industry, including：Framework（Generally adopt
Use aluminum frame）, the solar energy photovoltaic glass being installed in framework, be located at solar energy photovoltaic glass below cell piece（Also referred to as silicon chip
Or silicon plate）, hot melt adhesive layer（EVA layer）, rosette and backboard（Backboard is also referred to as insulating back panel）.
In view of non-renewable natural resourcess such as oil, coal, natural gas and ocean ice is increasingly deficient, and the in view of mankind
To the economy consciousness of natural resourcess and significantly increasing for protective awareness, to inexhaustible and have the feature of environmental protection and
The utilization of cheapness resource such as wind energy and solar energy is paid attention to increasingly, ground of the solar energy in the sustainable use energy strategy of the mankind
Position increasingly shows.
Solaode is one of core component in solar photovoltaic generation system, and which is by a group for arranging in advance
Crystal silicon cell is laminated on ultrathin transparent and constitutes between the glass of high intensity and sealing bottom, and sealing bottom is
Backboard, as backboard plays the weather resistant protection of sealing to crystal silicon cell, therefore the quality of its quality is directly connected to the sun
The service life of energy battery.More particularly, service life usually requires that >=30 years, and therefore backboard used for solar batteries only has
The standby weatherability that stands out from one's fellows, resistance to ag(e)ing, insulating properties, contamination resistance are strong, water vapor transmittance（Sealing）Low and shelf depreciation energy
The features such as more than ＞ 1000V, could be adapted with the service life of solaode.
Prior art, is particularly no lack of the technology letter being seen in regard to backboard used for solar batteries in disclosed patent documentation
Breath, such as Chinese patent CN101582458A, CN101582459A, CN201387885Y, CN201387887Y,
CN101615636A, CN101431108A, CN101992571, CN101992572A, CN101979247A and
CN101964371A, etc..And for example United States Patent (USP) US3133854, US513989 and US6632518, etc..It is not limited to enumerate
These patents be both for weatherability, resistance to ag(e)ing, insulating properties, yellowing resistance and the water vapor barrier property of backboard and propose.
As is known in the industry, solaode（Custom claims photovoltaic cell, as follows）Part in daylight can be subject to purple during work
Outer light and substantial amounts of infra-red radiation, wherein, a length ultraviolet light can only also produce a hole-electron pair, and unnecessary energy turns
Turn to heat energy to discharge, infra-red radiation does not have the delivery efficiency of solaode any front to help, and can only be changed into heat
Can, while distinctive coupled thermal effects can be produced also in optical-electronic transformation process, if effectively can not radiate, set of cells will be caused
The temperature of part is raised.According to the characteristic of semiconductor of crystalline silicon, temperature often raises 1 DEG C, and it is left that its optical-electronic conversion efficiency will drop 0.4%
Right.In order to avoid shining upon the temperature for affecting battery module, and then the generating efficiency of impact battery module, thus to solar energy
The heat dispersion of battery backboard is more harsh.
The material of the basic unit in the structural system of the backboard used for solar batteries in prior art is usually poly- terephthaldehyde
Sour glycol ester（PET）, as the heat conductivity of PET itself is relatively low, thus constrain backboard heat conductivity to a great extent
Improve.
As shown in the above description, the thermal diffusivity for improving backboard can both reduce the internal temperature of solar module and have
Help protect solar module, the optical-electronic conversion efficiency of solaode can be improved again.
Equally visible all radiating effects for being intended to improve backboard used for solar batteries in disclosed Chinese patent literature
Technical information, typical such as CN102544380B recommend have " a kind of solar cell backboard and preparation method thereof and a kind of sun
Energy battery ", its are that in the single or double coating organic insulator of metallic plate, organic insulator contains with a metallic plate as carrier
There are titanium dioxide, polyimides and heat filling, and titanium dioxide is coupling agent modified titanium dioxide.The heat conductivity of backboard can be made
Reach 1.2w/m k.But there is the shortcoming that water vapor transmittance is big and polyimides are easily aging, color inhibition and ageing-resistant performance
It is difficult to the expection for meeting industry.And for example CN104103705A is provided with " heat radiating type solar energy backboard ", and which is seven-layer structure, wherein
Three layers is conducting adhesive layer, and two-layer is fluorine film, and one layer is PET, and another layer is metal basal board.Although the patent application scheme is to viscous
Knot layer has been made to improve, that is, employ conducting adhesive layer and employ metallic plate, but limited by PET low thermal conductivities, with
Sample is not enough to reach the desired radiating effect of industry, while back board structure is complicated and in use i.e. under arms in the time limit
There is the anxiety of tack coat failure." high radiating solar cell backboard " that CN103681915A is introduced equally exist with aforementioned
The shortcoming of CN104103705A.
In view of above-mentioned prior art, it is necessary to improved, for this purpose, the applicant has made beneficial design, will be detailed below
The technical scheme of introduction is produced under this background.
